将ICU VS2013解决方案移植到VS2015时发生C2248错误

Question

I am trying to port ICU 4.0 VS2013 solution to VS2015, while porting I get following error

Severity Code Description Project File Line Error C2248 'icu_4_0::Format::Format': cannot access protected member declared in class 'icu_4_0::Format' i18n c:\\research\\releases\\gtlib\\gtlib_6.0\\source\\aglc\\aglc40\\source\\i18n\\unicode\\measfmt.h 72

this is how function is defined:

protected:

/**
 * Default constructor.
 * @stable ICU 3.0
 */
MeasureFormat();

and class is defined as follows

class __declspec(dllexport) MeasureFormat : public Format {

I am unable to figure out what is causing the error.

Answer 1

solved this Bug base class(Format) was causing problem, base class must have copy constructor as well as assignment operator both should be public, It wasn't working when they were protected (atleast in my case).
